Agent S wears a blue helmet emblazoned with white stripes and the number 2. While her arms and legs appear to be striped, examining the gray and white colors of her tail and face reveal that these blue stripes are additional clothing rather than fur. She has circle-shaped eyes. Her initial look is the Number 2 shirt like the 2 on her helmet.

Below is a brief description of the peppy personality. For more information, click here.

As a peppy villager, Agent S will have the tendency to over-react in conversations about trivial subjects such as appearing in competitions and the chance of her losing. This sometimes triggers her to ask for a certain item of clothing or furniture which she needs to enter a competition. She, like other peppy villagers, will rarely be discouraged from doing anything, including the usual hobbies. She will also have a short attention span, which means she will soon forget arguments or tasks given to the player which were not completed. Agent S may ask the player; "Sooo, how am I dressed today?" The player is presented with a slide-bar indicating Kinda slobby... and Super formal! Moving the bar close to Super formal! will make her happy, thus giving a good chance of receiving her picture (in Wild World only).

In Animal Crossing: Wild World, Agent S owns many items from the Cabana Series, including the lamp, the bookcase, and the bed, the latter of which being situated in the middle of the room. She also owns a Classic Clock, a harp, and a birdcage. She also owns a High-End Stereo, which plays the song K.K. Cruisin'. Her choice of wallpaper is the Cityscape Wall, and her flooring is the Mosaic Tile.

In Animal Crossing: City Folk, Agent S' house is extremely similar to her Wild World house, with the only difference being that most of the furniture has been moved around.

In Animal Crossing: New Leaf, Agent S' house has more of a jock theme to it. She has the default basement wallpaper and flooring. In addition to this, she also owns a few boxing themed items, some examples being the boxing mat and the blue corner. She also owns a claw-foot bathtub, a drip pail, and a clothes closet. Agent S also owns a CD Player, which plays DJ K.K., contrary to all of her other appearances where she had K.K. Cruisin'.
